CORPORATION or MASSACHUSETTS MATERIAL FOR SCQTIRING UTENSILS Applicationfiled December 4, 1930. Serial No. 500,022.

This invention relates to an improved arrangement of material forscouring utensils. A particular utensil 'in which the new material canbe used to advantage is shown in my copending application Serial Number474,- 551, filed Augutt 11, 1930, i

In utensils of'this'general character, the common practice has been touse a textile carrier, cord on which a flattened metallic filament istwisted. The twisted or gimped filament provides scouring edges. Myinvention consists in changing the character of the carrier around whichthe metallic filament is twisted. In one form of the invention I use thesame kind of filament for the carrier as is used for the element twistedabout the carrier. To increase the effectof this change I may use two ormore such filaments inste'ad of one for the carrier means and twist oneor more filaments about the carrier means. The latter combinationgives-a loose bundled arrangement of the carrier filaments which are nottwisted to carry the filament or filaments which are twisted. By the newcombination more scouring edges are provided than in the old, and otheradvantages are obtained as will be pointed out with respect to theutility of a scouring utensil with the new arrangement of material.

A complete understanding of the invention is given by the accompanyingdrawings and description of the advantages in the new combination. Inthe drawings- Fig. 1 is a plan and Fig. 2 is an end view of the carriermeans in multiple form;

.--.Fig. 3 is a View of the carrier filament with another filament oflike character twisted about it into gimped form; and

Fig. 4 is a view of a scouring utensil such as is made up from thematerial shown in Fig. 3.

The filament 1 is or may be made of copgiven an anti-rust treatmentor ismade of an anti-rust alloy. It is such a filament as has been usedordinarily for the twisted part of the made-up strand in a scouringutensil of my type, but may differ by providing a stronger filament. Asa modification I may rier filaments break, but the latter 'will functionto scour in any event. T 0 practice my new invention I use a singlefilament 1 or a plurality of them, as shown in Fig. 2, as the carrier,and twist about it coils 2'of another filament of about the same kind.But the filaments 1 and 2 are all flattened so as to present scouringedges. The carrier 1, while it is not purposely. twisted, maynevertheless turn somewhat. The gimped or twisted strand 2 is looselymounted. on the carrier 1 with many turns to the inclrabout carrier 1 toincrease the scouring edges.

When the combination of Fig. 3 is used in a scouring utensil the coilsof strand 2 being loose are spread apart and pushed together, due to therubbing action. When they spread apart the edges of metallic strand orstrands 1 occupy the space between and are in a position. to functionalso as a scouring element and as a scraping element at the points wherethe coils have separated widely.

In a scouring utensil such as shown in Fig. 4 the total effectivescouring surface is greatly increased by the new arrangement orcombination of material .making up the utensil.

-'And this would be true also if other specific forms of scouringutensils were made up of the new arrangement of material.

The utensil shown in Fig. 4 is made up except for the material of thecarrier cord like the one more fully described in the above referredto'copendmg case. That is, the combination of carrier filament 1 andcoiled filament 2, as shown in Fig. 3, is looped into skein form. Eachskein loop passes twice through two circular binding'elements 4 and 5.By arranging the binding elements 4.- and 5 at directly opposite pointsin the skein loops, the material of theskein between the bindingelements is left in loose but regularly arranged form. The result ofsuch arrangement with the material shown is like a puff ball. The efiectis improved by the character of the carrier filament. There is 'ustenough spring in the metallic carrier to e ect a better holding of orreturn to the puff ball shape after use. In other words,'the carrier 6filament makes the utensil just a little stifier in form and yetyieldable enough for its function. The filaments which carry the gimpedstrands can and do act as scouring and scraping elements where thegimped strand is 10 moved along orspread out. Furthermore,

the bright appearance of the ball when made entirely of flattenedfilament is enhanced. The binding elements t and 5 are preferably ofstiff wire so the whole utensil is of metal but in form to beeasilyoleaned.

\Vhat I claim is: 1. The combination for scouring purposes oftwofiattened metallic filaments, one arranged as a straight strand forcarrying the other and the latter loosely coiled or gimped about thefirst so that the combined all-metal strand has scraping edgesthroughout its length, some on the "carrier strand and some on thegimped strand. 2. An improved structure for scouring purposes of aplurality of loosely arranged parallel flattened metallic filaments inuntwisted form and providing a carrier means, a metallic filamentloosely twisted or gimped about the carrier means to make with thecarrier a composite scouring strand in which scouring edges are providedby both the carrier and the gimped elements.

In testimony whereof I have affixed my signature.
